Key Features to Look For in River Tubing Dry Bags

River tubing exposes gear to unique stressors that differ from casual pool use or flatwater kayaking. Tubers spend hours low to the water, meaning gear is constantly sitting in a puddle at the bottom of the tube or getting scraped against shallow river beds and low-hanging branches. Standard water-resistant bags will saturate over time; true waterproof ratings are mandatory.

Look for heavy-duty materials like TPU (Thermoplastic Polyurethane) or high-denier nylon with welded seams rather than stitched ones. A reliable roll-top enclosure requires at least three tight rolls to create a seal, while submersible zippers need an airtight IPX7 or IPX8 rating to survive full submersion.

Finally, pay close attention to anchor points. Heavy-duty D-rings, webbing loops, and integrated lash points are critical for securing the bag to the tube’s handles or perimeter lines. Without a secure way to tie down the gear, even the most waterproof container will float away downriver if the tube capsizes in a sudden rapid.

Dry Bag – Sea to Summit Big River Dry Bag

A heavy-duty dry bag serves as the primary storage workhorse for a day on the river, holding bulkier items like towels, spare shirts, and lunch. It bridges the gap between flimsy lightweight sacks that puncture easily and overly bulky hard cases.

The Sea to Summit Big River Dry Bag excels here because of its incredibly tough construction and stable design.

• Material: 420D waterproof nylon
• Best For: Clothes, towels, and bulk storage
• Sizes: 5L to 65L (20L recommended for tubing)

While virtually indestructible under normal recreation, this roll-top bag is not rated for prolonged underwater submersion. It relies on a proper seal, meaning users must roll the top tightly at least three times to keep water out during a flip. It is available in multiple sizes, though the 20L size is generally the sweet spot for a single tuber’s daily gear.

This bag is perfect for recreational tubers who need rugged, puncture-resistant storage for clothes and snacks without paying premium zipper prices. It is not the right choice for high-value cameras or non-waterproof electronics that require guaranteed submersible protection.

Waterproof Backpack – YETI Panga 28 Airtight Backpack

A waterproof backpack keeps hands free during the launch and portage stages of a river trip while keeping gear secure and dry during the float. It allows for easy transport from the parking lot to the water’s edge, especially when navigating muddy banks or slippery rocks.

The YETI Panga 28 Airtight Backpack is a fortress of a pack, offering absolute protection from water ingress.

• Material: ThickSkin Shell
• Best For: Tech, cameras, and multi-use daypack travel
• Waterproof Rating: IPX8 Submersible

This level of protection comes with a premium price tag and a zipper that requires occasional maintenance. The airtight zipper has a noticeable pull resistance and needs to be lubricated regularly with the included zipper lubricant to prevent tearing or jamming. It is a structured, stiff pack that does not compress, so it requires dedicated space inside or lashed to the tube.

This backpack is ideal for tech-heavy tubers, photographers, or those tackling wilder, semi-active rivers where flipping is a real possibility. It is overkill for casual floaters who only need to keep a towel and a sandwich dry on a calm, lazy creek.

Phone Case – JOTO Waterproof Phone Pouch

Phones are the most vulnerable and frequently used items on the river, requiring constant protection that still allows for taking photos and navigating. A reliable phone pouch hangs around the neck, keeping the device instantly accessible while shielding it from wet hands and sudden drops.

The JOTO Waterproof Phone Pouch offers simple, highly effective protection with a clear, user-friendly design.

• Material: Clear PVC
• Best For: Smartphones, ID cards, and cash
• Waterproof Rating: IPX8 certified (up to 100 feet)

High summer heat can cause condensation to build up inside the pouch, so it is wise to throw in a tiny silica gel packet if floating on a humid day. Additionally, touchscreens do not register inputs well underwater due to water pressure, so physical volume buttons must be used to snap photos if the phone gets submerged.

This is a must-have, low-cost insurance policy for anyone bringing a smartphone onto the water. It is not designed for bulky, ruggedized phone cases, which may require removing the phone from its daily case before sliding it into the pouch.

Waterproof Dry Box – Pelican 1040 Micro Case

Delicate, crushable valuables like car keys, key fobs, wallets, and medication cannot risk being compressed or damp. A small, rigid dry box protects these small items from crushing forces when gear is stacked or stepped on inside the tube.

The Pelican 1040 Micro Case is legendary for its crushproof construction and reliable o-ring seal.

• Material: Polycarbonate
• Best For: Key fobs, wallets, and medications
• Special Feature: Automatic pressure equalization valve

The interior dimensions are compact, so users must measure their items—especially larger modern smartphones or bulky key rings—before purchasing. It does not float automatically if heavily loaded, so clipping it to a secure line using the integrated carabiner loop is highly recommended.

This case is perfect for tubers carrying high-value, fragile items like electronic keys, memory cards, or daily medications. It is not suitable for bulkier items or those looking for a lightweight, flexible storage solution.

Waterproof Duffel – NRS Expedition DriDuffel

When tubing as a group or packing for an all-day river expedition, a waterproof duffel provides the massive volume needed to carry group gear, dry clothes for everyone, and camp blankets. Its wide-mouth opening makes retrieving items much easier than digging through a deep, narrow dry bag.

The NRS Expedition DriDuffel is built from heavy-duty, environmentally friendly materials designed to handle the rough-and-tumble environment of gravel bars.

• Material: PVC-free TUSA fabric
• Best For: Group gear, camping gear, and sleeping bags
• Closure: Fold-down storm flap with rugged zipper

Because this is a large-format bag, it can quickly become too heavy to manage if overloaded. It is designed to sit flat, meaning it takes up significant real estate and is best suited for larger lounge tubes or dedicated gear-tracking rafts towed behind the group.

This duffel is best for families, group leaders, or multi-day river campers who need to pack high volumes of gear securely. It is not recommended for solo tubers on standard-sized round tubes due to its bulk and footprint.

Floating Cooler – CreekKooler Pup Floating Cooler

Keeping drinks and lunch cold is essential for a hot day on the river, but dragging a standard hard cooler on a separate tube creates drag and instability. A dedicated floating cooler slides effortlessly across the water’s surface, keeping refreshments cold without disrupting the float’s rhythm.

The CreekKooler Pup Floating Cooler features a unique, hydrodynamic hull design modeled after a kayak, allowing it to glide over river obstacles and through light rapids with ease.

• Material: Dual-wall roto-molded plastic
• Best For: Drinks, ice, and food preservation
• Capacity: 15 cans and 10 lbs of ice

The “Pup” version is perfect for small groups but requires careful packing to maximize space. It must be towed behind a tube using a tow rope, which requires awareness of river obstacles to prevent the tow line from snagging on low branches or rocks.

This is the ultimate accessory for social tubing groups who want easy, cold beverage access without sacrificing tube space. It is not necessary for solo, short-duration floaters who can get by with a small, insulated soft cooler tucked inside their main tube.

Waterproof Waist Pack – Patagonia Guidewater Hip Pack

A waist pack keeps critical, quick-access items like sunscreen, sunglasses, lip balm, and snacks securely strapped to your body. This eliminates the need to constantly reach into a secured dry bag behind your head while floating down the river.

The Patagonia Guidewater Hip Pack is fully submersible and built with premium, water-shedding materials.

• Material: 100% recycled nylon with TPU coating
• Best For: Sunscreen, quick snacks, and small essentials
• Waterproof Rating: IPX7 Submersible

To ensure a completely waterproof seal, the zipper must be pulled completely closed into its “docking” garage at the end of the track. The waist strap is adjustable, but users should wear it snug to prevent the pack from floating up around the chest when sitting low in a tube.

This pack is ideal for active tubers who want instant access to essentials while keeping them 100% dry and securely attached to their body. It is not the right choice for those on a tight budget, as it represents a premium investment in specialized waterproof gear.

Hard Case – Plano Guide Series Waterproof Case

A medium-sized, hard-sided waterproof case provides structured protection for mid-sized electronics, cameras, or first-aid kits that cannot handle being compressed. It acts as a safety vault within the tube, protecting contents from both water ingress and impact damage.

The Plano Guide Series Waterproof Case stands out with its rugged, cam-action latches and highly protective interior lining.

• Material: Rigid molded plastic with TPR lining
• Best For: Action cameras, power banks, and fragile gear
• Seal: Dri-Loc O-ring

While highly impact-resistant, the rigid plastic exterior can scratch over time if dragged across gravel bars. It is important to inspect the O-ring periodically for sand or debris, as a single grain of river sand can compromise the waterproof seal.

This case is perfect for tubers carrying action cameras, battery banks, or delicate personal gear that needs structured protection. It is not suitable for those who need flexible, packable storage that can conform to tight spaces inside a dry bag.

Dry Sack – Earth Pak Waterproof Dry Bag

A lightweight dry sack is the perfect everyday solution for keeping basic gear dry during casual river floats. It acts as a reliable shield against splashes, paddle drips, and brief dips, making it a staple accessory for recreational water sports.

The Earth Pak Waterproof Dry Bag is crafted from heavy-duty, commercial-grade materials, offering exceptional durability at a very accessible price point.

• Material: 500D PVC
• Best For: Budget-friendly storage and day trips
• Bonus: Included waterproof phone case

PVC material can stiffen in colder water, making it slightly harder to roll tightly on chilly spring days. Users should always fold the top down at least three to four times and ensure the buckle is securely clicked to maintain water resistance.

This dry sack is the ideal choice for casual, budget-conscious tubers looking for dependable protection for towels, sunscreen, and dry clothes. It is not meant for extreme, high-impact whitewater or situations where the bag will remain submerged for long periods.

How to Secure Your Waterproof Gear to a River Tube

Simply throwing dry bags and hard cases into a river tube is a recipe for lost gear, as river currents can easily sweep unsecured items away during a capsize. Even on the calmest lazy rivers, unexpected submerged logs, shallow rocks, or passing watercraft can tip a tube in an instant. Securing gear properly ensures that if the tube flips, the gear flips with it and stays attached.

The most effective way to secure gear is by using high-quality cam straps or marine-grade bungee cords threaded through the tube’s grab handles or perimeter rope. Heavy-duty aluminum carabiners are excellent for quickly clipping dry bag D-rings directly to the tube’s integrated attachment points. Avoid using flimsy plastic clips or weak ropes that can snap under the tension of moving water.

When lashing gear down, balance is key to maintaining a stable, comfortable ride. Position heavier items, like dry boxes or coolers, low and centered within the tube or in a trailing gear tube to prevent the main tube from tipping. Keep essential items like phone pouches and safety whistles clipped close to the body for quick, hassle-free access.

Cleaning and Drying Your Gear After a Day on the Water

River water contains sand, silt, microorganisms, and organic matter that can degrade waterproof coatings and ruin zippers if left unattended. Neglecting post-trip cleaning leads to mold, unpleasant odors, and compromised seals that will fail on the next excursion. Taking a few minutes to clean gear immediately after a float extends its lifespan significantly.

Rinse all dry bags, cases, and packs inside and out with fresh, clean tap water to flush away abrasive silt and river grime. For stubborn mud or river smells, use a mild, non-detergent soap and a soft-bristled brush to gently scrub the exterior surfaces and zipper tracks. Avoid using harsh chemical solvents or abrasive pads, which can strip away critical polyurethane waterproof coatings.

Hang dry bags upside down with the roll-tops wide open in a well-ventilated, shaded area out of direct sunlight. Ensure hard cases are left open with O-rings exposed until completely dry to prevent mold from forming in the seals. Once entirely dry, store the gear in a cool, dry place away from extreme temperatures and UV exposure to keep it ready for the next adventure.

Conclusion

Investing in high-quality waterproof storage transforms a standard river float into a worry-free day of pure relaxation on the water. By selecting the right combination of rugged dry bags, secure hard cases, and reliable tethering gear, every item brought along will return home safe and dry. Pack smart, secure everything tightly, and enjoy the perfect, stress-free lazy river adventure.
